AMD released the Radeon RX 7900 XTX and Radeon RX 7900 XT graphics cards based on a new generation of RDNA 3 architecture GPUs on November 3. The former has 6144 stream processors, 24GB of GDDR6 memory, and a power consumption of 355W; the latter stream processing There are 5376 devices, 20GB GDDR6 memory is used, and the power consumption is 300W. Both graphics cards have been officially listed on December 13.
According to previous reports, some users reported that the junction temperature of Radeon RX 7900XTX can easily reach 110 degrees in high-load scenarios such as 4K games. The user tried to increase the fan speed of the graphics card, but the phenomenon of frequency reduction still occurred. Finally, the user proposed to return the product. Requested a refund, but was rejected by AMD.
Citing Tom’s Hardware news, AMD recently issued an official statement saying that only a small number of users have encountered this problem on the Radeon RX 7900XTX, and users who encounter this problem should contact AMD official support.
The junction temperature is the actual operating temperature of the semiconductor in the electronic device. It is called “Junction temperature” in AMD’s official driver and shows the internal temperature of the core. The junction temperature is generally 15-25 degrees higher than the conventional graphics card temperature. Previously, the upper limit of the junction temperature set by AMD for the RX 5700 graphics card was 110 degrees.
According to AMD, 110 degrees is the normal junction temperature of Radeon RX 7900XTX. At present, it is suspected that the uneven contact pressure between the radiator and the core will cause the overheating problem of the graphics card. Some users say that re-pasting or replacing the thermal pad is a feasible solution. The AMD team is investigating this issue, and PowerColor is collecting user feedback to assist with the investigation.
AMD has not given a specific date for solving the problem, and some users have reportedly returned their Radeon RX 7900XTX graphics cards.
